Integrated Pressure Bearing Type

Advantages

• Can be operated automatically if connected with intelligent controller.
• Simple structure, easy plug-in installation, can be installed both on flat and inclined roof, and can be used with an auxiliary electric booster as to provide hot water without sunshine.
• Superior heat preservation ensured by one-off molding polyurethane foam with thickness 55mm.
• Suitable for camping area, holiday residences.
• Stable and reliable performance, well wind resistance.
• Meet the mankind healthy bath standard: The material of inner tank is SUS304-2B stainless steel plate; the silica gel ring sealing has a long life against the erosion and it not harmful to health.

In terms of the tank which is the most important core of a solar water heater. We are testing every tank before they leave the factory, and most importantly, we are testing the leakage by auto leakage testing machine, which will have a much higher testing pressure and longer testing time.

Heat Pipe Vacuum Tube

• Heat resistance: 0.02℃/W
• Transfer Power:≥150W
• The best angle: 30~60
• Working Pressure: 4×106 Pa
• Welding Pressure: 4M Pa
• The temperature ranger of antifreeze heat pipe: -30℃~300℃ 

The Principle of Vacuum Tube

Sunny has developed a water heater which combines heat pipe solar collector and storage tank into one product. The condenser of the heat pipe tube is directly inserted into the non-corroding copper protection tube within the water tank. The heat pipe evacuated tube collect heat with high efficiency transforming of the incoming solar irradiation into heat.

The condenser transfers the generated heat to the manifold where the water is heated. Thereafter, the hot water is circulating in the system until the system attains the required temperature.

Advantages

• Adopts the best conduction performance metal- heat pipe (copper).
• Start up quickly, heat pipe transfer the heat energy into the storage tank in one direction
  
• No water inside the evacuated tubes, the solar water heater can still in service even with several tubes breakage
• Can be used all year round in the cold climate
  
• No maintenance

In terms of the electric element, we are adopting the best Electric heater, with in glass structure. (Fig. 1)

You can find that the electric heater was not immerged inside the water directly; they are protected by the glass cover made of quartz. And this structure will strengthen the life span of our electric heaters and also can offer a best clean hot water comforts. 

Meanwhile; in other brands, they only choose normal stainless steel electric heaters. (Fig. 2)

Magnesium Stick

We provide Magnesium stick (to protect inner tank form corrosion).

Features:

• Made of magnesium 'Magnesium Stick'
• Anode Protection
• To keep the water clean

Intelligent Controller

This controller (TK-7Y) can control the electric heating either automatically or manually.

It can show the temperature of the water & it is easily adjusted according to your desire.

Desription:

• Dimension: 20cm*13.5cm*3.8 cm
• Use Power Supply: AC 220V±10%
• Self Power Consumption <3W
• Measuring Accuracy of Temperature: ±2
• Controllable electric heating power 2000 W
• Water Protection Grade IP42
• Time display 24-hour clock display time
• Temperature Indicator: The actual display water tank temperature
• Time Heating Auxiliary heating temperature control three time periods
• Manual heating according to Manual button to start the electric heating to a pre-set temperature of cessation of heating

Assitant Tank

The small tank of stainless steel guarantees that the tank is always full of water all the time

Products Features:

• Supplying water automatically and stop working when the big tank is full, it can serve 24hours in a day.
• Its operation basics on the gravity and float ball, environment friendly and power saving.
• The temperature of big tank will fall down evenly; the users never suffer the hot-cold water suddenly.
• The big tank is always full, so the big tank can resist higher strong wind power

Warranty

10 years for vacuum tubes and main bod; except for improper use and natural disasters
